HENRIK IPSEN, OF NEW YORK, N. Y.

MUSIC-LEAF TURNER.

To all whom it may concern:

Be it known that I, HENRiK IrsEN, a citizen of Denmark, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

This invention relates to music leaf turners of that type including a plurality of spring actuated arms which are held in set position by a key that is pressed by the musician each time a leaf is to be turned.

The invention has for one of its objects to improve and simplify the construction and operation of an apparatus of this character so as to be comparatively simple and inexpensive to manufacture, reliable and eflicient in use and readily manipulated.

Another object of the invention is the provision of a folding music leaf turner including a novel arrangement of turning arms.

Another object of the invention is to provide an eflicient, simple and novel means for successively releasing the leaf turning arms.

An additional object is the employment of an attachment whereby the device can be adapted for sheet music, the attachment serving as a lock for holding the leaf turner open for use. 7

With these objects in view, and others as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention; Figure l is a front view of the device showing the attachment applied thereto for sheet music. Fig. 2 is a plan View of the device in closed or folded position. Figs. 3 and 4 are detail sectional views showing the means for releasably holding the leaf turning arms in said position and for releasing them in successive order. Fig. 5 is a perspective View of one of the leaf turning arms. Fig. 6 is a perspective view of the standard of the attachment. Fig. 7 1s a fragmentary perspective View of the hingedly connected portions of the two sections of the device, shown in open or unfolded position. Fig. 8 is a plan view of Fig. 7 with portions broken away showing the sections locked open by the standard Specification of Letters Patent. Application filed March 16, 1910.

of the attachment being inserted. Fig. 9 1s a perspective view of one of the clips of the attachment for holding a piece of sheet music. Fig. 10 is an enlarged end view of the music leaf turner when folded.

Similar reference characters are employed to designate corresponding parts throughout the several views.

Referring to the drawings A designates a bar-like support which is adapted to rest on the music holder of an instrument or of a music stand and it is of such width that the music book can rest with its bottom edge thereon. This bar or support A constitutes a rest on which the bottom of the music bears and is preferably hollow from end to end and open at one side or in other words is channel-shaped in cross section and consists of two sections 1 and 2 joined at the center of the support by a hinge 3 so that the two sec tions can fold back on each other to reduce the length of the device when it is to be packed for carriage. The front side of the bar or support A is open so as to accommodate the leaf turning arms B, of which, in the present instance, there are four and, as shown in Fig. 2, the arms are housed within the two sections thereof since the open sides of the sections meet when the device is folded or closed.

Each leaf turning arm B is preferably constructed of a single piece of sheet metal punched and formed into the desired shape by machinery. At one end of the arm is formed a pair of spaced lugs 4 that have apertures 5, as shown in Fig. 5, for receiving the pintle 6 of the hinge 8 and each arm is adapted to swing through an arc of 180. Each arm is provided with spaced clips 7 and 8 for attaching the bottom edge of a music leaf thereto. Each clip consists of an upstanding jaw 9 rigid on the bar and with which cooperates a movable jaw 10 that is carried by a leaf spring 11 formed by providing spaced slits 12 in the middle of the arm and stamping out the intervening portion. The jaws consist of a plurality of upstanding connected members or fingers which are disposed opposite each other for effectively gripping the leaf of music. In opening the movable jaw, the spring 11 is pressed laterally against its tension, and while held in this position, the music leaf is inserted between the jaws so that when the spring is released, the jaws will close. On the pintle 6 are arranged four helical springs 13, there being one for actuating each arm B and the springs are so arranged that when the arms are set, the springs will be under tension so as to throw the arms to the left when they are released to turn the leaves. The top flange 1 1 of the bar or music support A has recesses 15 for accommodating the jaws 7 and 8 of the leaf turning arms.

The device C for releasably holding the jaws in set position will be understood more clearly by reference to Figs. 1, 3 and 4. The said device, which is mounted on the right end of the right hand section 2 of the music support A consists of a pivoted key or lever 16 that has a depending finger piece 17, whereby the key or lever can be depressed, there being a spring 18 interposed between the finger piece and bar A so as to yieldingly hold the key in locking position. The key has a laterally extending member or projection 19, which engages the extremity of the fcremost arm B so that when the key is depressed, the member 19 will release the arm and permit the same to turn the music leaf attached thereto. hen the foremost arm is thus released, it is necessary to hold back the other arm or arms and for this purpose a hold back latch 20 is fulcrumed at 21 in the bar or support A and is adapted to be automatically thrown to and from arm engaging position by themanipulation of the key 16. For this purpose the key or lever 16 is provided with a projection 22, which is adapted to engage a projection 23 on the latch 20 and hold the latter in disengaged position as shown in Fig. 3, and connected with the latch 20 is a spring 24, which tends to throw the latch to arm engaging position when the key is depressed at which time the projection or'shoulder 22 moves away from the shoulder or projection 23. It will thus be seen that when the key 16 is depressed or moved from the position shown in Fig. 3 to that in Fig. 4, the latch 20 will be released so that itwill move by the tension of the spring 24 to engage the shoulder 25 with the outermost arm following that which has been released by the member 19 of the key when the latter are depressed. As soon as the finger is released from the key, the spring 18 will expand and throw the key back to normal position so that the member 19 will be disposed in front of the next arm B to catch the same when the back-ho] ding latch is released from such arm by the shoulder 22 striking the shoulder 23. By this co-action of the parts 19 and 20, which may be considered as pawls, the leaf turning arms will be successively released by the successive actuations of the key 16.

The apparatus above described is especially adapted for bound music in book form, since the book will rest on the support A and it is merely necessary to attach the leaves to be turned to the clips of the arms B since the device itself will not have to support the leaves. hen sheet music is to be used, an attachment, designated generally by D, is employed in connection with the apparatus already described. This attachment consists of a standard 26 composed of flat strips or sections a and Z) slidably connected by inturned lugs 27 on the section Z) engaging opposite l edges of the section a so that the standard can be extended or contracted according to,

the size of the music sheets. This standard is attached to the music support or bar A in such a manner as to,form a lock for holding the sections 1 and 2 in open or unfolded position, hence the lower end of the standard section b is provided with a longitudinal slot 28 so that two members 29 are formed and these members engage, respectively, in slots 30 at the meeting ends of the sections 1 and 2 of the support A, as clearly shown in Fig. 7. The back walls 31 of the sections 1 and 2 are turned in wardly at 32, Fig. 8, so as to form passages 33 for receiving the members 29 of the standard, the passages extending to the bottom of the sections so that the members 29 can be inserted substantially their full length to those holding the standard upright and atthe same time lock the two sections 1 and 2 of the music support A in open position. On the upper end of the section a. of the standard are forwardly projecting lugs 34 for supporting leaf gripping clips 35, each of which is a single piece of sheet metal stamped into fixed and movable jaws 36 and 37 and provided with pintles 38, as shown in Fig. 9, to engage in the bearing lugs 34, the movable jaw being connected with a body 39 of the clip by a spring 10. In using the attachment D, the leaves of the sheet music have their bottom edges connected with the clips 7 and 8 of the arms B and the upper inner corners of the respective leaves are connected with the clips on the standard. In this manner the sheet music will be stably supported.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention relates, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the apparatus shown is merely illustrative and that such changes may be made when desired as are within the scope of the claims.

hat I claim as new and desire to secure by Letters Patent is 1. A music leaf turner comprising a pair of bars of channel cross section and hinged together at their inner extremities, said inner extremities having recesses adapted to aline to form slots, a device entered in the slots to lock the bars in open alining position, and music turning elements operatively connected with the bars and adapted to be housed Within the same When the bars are closed against each other.

2. A music leaf turner comprising tWo sections hinged together and having recesses in adjacent ends adapted to aline to form slots, a locking device removably inserted in the slots to hold the sections in open alining position, a pintle hingedly connecting the sections together, a plurality of music leaf turning elements mounted on the pintle, springs coiled around the pintle and each engaging a leaf turning element for operating the same, and means mounted on one of the sections for controlling the turning of the elements.

3. A music leaf turner comprising a pair of hingedly connected sections, means engaging said sections for locking the same in open alining position, said means comprising relatively adjustable sections, one of said sections being adapted to engage said hing'edly connected sections, and means carried by the other adjustable section for engaging a sheet of music.

In testimony whereof I aflix my signature in presence of tWo witnesses.

HENRIK IPSEN.
